We have a job which runs throughout the day which sends emails out if there is data to be reported. Some of this data is reported in csv files as the data needs to be sent to external businesses so they can load it into there systems. If the process tries to send a non attachment email having just sent an email with an attachment the job fails and returns an error of "probably invalid parameters". We have run a profiler to try and get a better error and we thought we had fixed the issue by separating the emails into different stored procedures however we are still getting the error. Has anyone come across this issue before?
